CROSS REFERENCE TO RELATED APPLICATION

This application is a continuation-in-part of U.S. patent application Ser. No. 16/279,791, filed on Feb. 19, 2019, which claims priority to U.S. Provisional Patent Application No. 62/632,023 filed on Feb. 19, 2018, each of which is hereby incorporated by reference in its entirety.

FIELD OF THE DISCLOSURE

The disclosure relates to the field of plant breeding, and more specifically, to cotton variety FM 2498GLT. The disclosure further relates to vegetative reproduction of cotton variety FM 2498GLT, methods for tissue culture of cotton variety FM 2498GLT, methods for regenerating a plant from such a tissue culture and to phenotypic variants of cotton variety FM 2498GLT. The disclosure also relates to progeny of cotton variety FM 2498GLT and the hybrid varieties obtained by crossing cotton variety FM 2498GLT as a parent line with plants of other varieties or parent lines.

BACKGROUND OF THE DISCLOSURE

Cotton is an important, fiber producing crop. Due to the importance of cotton to the textile industry, cotton breeders are increasingly seeking to obtain healthy, good yielding crops of excellent quality.

Cotton is commonly reproduced by self-pollination and fertilization. This type of sexual reproduction facilitates the preservation of plant and variety characteristics during breeding and seed production. The preservation of these characteristics is often important to plant breeders for producing cotton plants having desired traits. Other methods of producing cotton plants having desired traits are also used and include methods such as genetic transformation via Agrobacterium infection or direct transfer by microparticle bombardment (see, e.g., US 2009/0049564).

Due to environment, the complexity of the structure of genes and location of a gene in the genome, among other factors, it is difficult to predict the phenotypic expression of a particular genotype. In addition, a plant breeder may only apply his skills on the phenotype and not, or in a very limited way, on the level of the genotype. As a result, a particular plant breeder cannot breed the same variety twice using the same parents and the same methodology. Thus, a newly bred variety is an unexpected result of the breeding process. Indeed, each variety contains a unique combination of characteristics.

By carefully choosing the breeding parents, the breeding and selection methods, the testing layout and testing locations, the breeder may breed a particular variety type. In addition, a new variety may be tested in special comparative trials with other existing varieties in order to determine whether the new variety meets the required expectations.

Development of Cotton Variety FM 2498GLT

The disclosure described herein has been obtained by a general breeding process comprising the steps outlined below (see, e.g., Introduction to Plant Breeding, 1967, Chapter 11, Briggs and Knowles, Rheinhold Publishing Corporation).

Parent plants, which have been selected for good agronomic and fiber quality traits are manually crossed in different combinations. The resulting F1 (Filial generation 1) plants are self-fertilized and the resulting F2 generation plants, which show a large variability on account of optimal gene segregation, are planted in a selection field.

These F2 plants are observed during the growing season for health, growth vigor, plant type, plant structure, leaf type, stand ability, flowering, maturity, seed yield, boll type, boll distribution, boll size, fiber yield and fiber quality. Plants are then selected. The selected plants are harvested, and the bolls analyzed for fiber characteristics and the seed cleaned and stored. This procedure is repeated in the following growing seasons, whereby the selection and testing units increase from individual plants in the F2, to multiple plant containing ‘lines’ (descending from one mother plant) in the F5 and the number of units decrease from approximately 2500 plants in the F2 to 20 lines in the F5 by selecting about 10-20% of the units in each selection cycle.

The increased size of the units, whereby more seed per unit is available, allows the selection and testing in replicated trials on more than one location with a different environment and a more extensive and accurate analysis of the fiber quality.

The lines or candidate varieties become genotypically more homozygous and phenotypically more homogeneous by selecting similar plant types within a line and by discarding the so called off-types from the very variable F2 generation on to the final F7 or F8 generation.

Depending on the intermediate results the plant breeder may decide to vary the procedure described above, such as by accelerating the process by testing a particular line earlier or retesting a line another year. He may also select plants for further crossing with existing parent plants or with other plants resulting from the current selection procedure.

By the method of recurrent backcrossing, (see, e.g., Briggs and Knowles, supra, in chapter 13, “The Backcross Method of Breeding”), the breeder may introduce a specific trait or traits into an existing valuable line or variety, while otherwise preserving the unique combination of characteristics of this line or variety. In this crossing method, the valuable parent is recurrently used to cross it at least two or three times with each resulting backcross F1, followed by selection of the recurrent parent plant type, until the phenotype of the resulting F1 is similar or almost identical to the phenotype of the recurrent parent with the addition of the expression of the desired trait or traits.

Cotton variety FM 2498GLT was derived from a backcross breeding program with a proprietary recurred line as one parent and a proprietary line as the donor parent which contained GLYTOL® and TWINLINK® proprietary technologies, which expresses tolerance to herbicides. The initial cross between the proprietary recurrent line and the proprietary GLYTOL® and TWINLINK® donor line was made in the greenhouse. Two generations of backcrosses to the proprietary recurrent line were then performed. Individual plants were selected for homozygosity in the BC2F2 generation. The following year, BC2F3 progeny rows were grown for seed increase. Then sister lines of this material were tested in several locations across the High Plains of Texas. Two lines were identified bases upon data gathered from replicated testing. These two lines were selected and bulked based upon performance and adaptations to the Texas High Plains.
